MAX3318EEAP

Overview

The MAX3318EEAP is a low-power, RS-232-compatible transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 2.5V supply and supports data rates up to 460kbps. The device integrates two drivers and two receivers in a full-duplex configuration. It features 15kV ESD protection on all RS-232 lines per IEC 61000-4-2 standards. The component is housed in a 20-pin SSOP package and is rated for operation within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated 15kV electrostatic discharge (ESD) protection on transmit and receive lines compliant with IEC 61000-4-2 standards.
• Single 2.5V power supply operation eliminates the need for dual voltage rails.
• Full-duplex communication capability with integrated charge pump circuitry.

Applications

• Portable battery-powered equipment requiring low current consumption
• Industrial control systems operating in electrically noisy environments
• Medical devices requiring robust ESD immunity

Procurement Notes

Verify the specific suffix 'EEAP' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure the procurement channel provides traceability documentation consistent with Analog Devices quality standards. Confirm that the component meets RoHS directives if required by the target assembly specifications.

Selection Notes

Select this component when designing systems powered exclusively by a 2.5V source. It is suitable for applications demanding high ESD resilience without external protection components. Verify that the required data rate does not exceed 460kbps and that the thermal environment remains within the specified -40°C to +85°C operational limits.

Part Context

This part belongs to the MAX3318E series of RS-232 transceivers designed for low-voltage applications. It serves as a direct replacement for legacy parts requiring higher voltage supplies, offering improved power efficiency while maintaining standard RS-232 signal levels through internal charge pumps.

Replacement Considerations
